Abstract

The invention relates to a disposable puncture endoscope used for attached observation of a puncture body in percutaneous nephrolithotomy, solving the clinical restrictions of poor puncture accuracy, big amount of bleeding, high operation failure rate and poor safety of the existing appliances used in percutaneous nephrolithotomy. The puncture endoscope comprises an ocular unit, an image transferring unit, a main endoscope body, a lighting unit and a puncture body. The puncture body is composed of a disposable puncture needle and an indwelling catheter. The disposable puncture needle comprises a hollow outer tube and a plastic needle body. The ocular unit is composed of an ocular cover, and an ocular glass and an ocular lens which are arranged inside the ocular cover. The image transferring unit is composed of a multi-filament image transferring rod arranged inside the hollow outer tube of the puncture needle. The front end of the main endoscope body is connected with the plastic needle body of the puncture needle and the back end of the main endoscope body is connected with the ocular cover of the ocular unit. The lighting unit is composed of a built-in lighting component and a detachable lighting component. The puncture endoscope has the advantages that the puncture endoscope is good in visibility during operations, high in puncture accuracy, less in bleeding, high in operation success ratio and high in safety and is unnecessary to be charged with water.

Description

technical field [0001] The invention relates to an endoscope for medical surgery, in particular to a puncture endoscope for percutaneous nephrolithotomy. Background technique [0002] Percutaneous nephrolithotomy is a new technology for the treatment of urinary calculi that has emerged in recent years. It uses special endoscopes, intracavitary lithotripsy and stone removal equipment to complete the treatment through percutaneous nephrostomy. As early as the 10th century in Arabia, there was a tradition of removing kidney stones through skin poking holes, but due to limited conditions and a low success rate, it has not been popularized and applied. It was not until the advent of percutaneous nephroscopy in the mid-1970s that this technology was relatively perfect and could be popularized and applied. my country introduced this technology and equipment from abroad in the early 1980s, first achieved success in Beijing, Guangzhou and other places, and then pushed it to the whol...
